In studies of immigration, generation is typically considered a static categorical system. I argue, however, that generation is a fluid construct and must be understood as place-based. Drawing on fieldwork conducted among Latino/as along the Texas–Mexico border, I seek to explore what current framings of generation leave out. Many in Laredo, Texas, see this border as allowing or preventing movement; these perceptions impact the constructions of generational categories. Cross-border travel, conceptualizations of place and immigration, and mixed-generational unions shape immigrant experiences, and in turn, affect concepts of generation. I conclude by offering ideas and inviting discussion on how the concept of generation can be re-worked to move beyond blunt categories and be re-conceptualized from the perspective of immigrants.
